The market demanded a powerful and rugged belt sander for larger jobs, and we responded with the Galaxy B12.

Same Machine, Brand New Look!

The 12” drum enables the floor sanding professional to cover 50% more surface area per pass than an 8” belt sander. Features include a 7.5 HP stall proof motor, patented tracking tension roller and a flat belt pulley system for more efficient power transfer. Modelled after the Omega 8, the B12 shares the same technology, but in a 12” machine. The Galaxy B12 is tough and delivers optimum quality with even less effort and time involved.

  • Tough
  • Delivers optimum quality
  • Requires less effort and takes less time


B12 Belt Sander Features


7.5 hp Motor
At the heart of all our floor sanders is a single phase, 7.5 hp motor, custom manufactured by Galaxy. This heavyweight exceeds the 4.5 hp industry average by over 66%! An optional 3-Phase 9.0 hp is available for industrial applications.

By loosening two release pins, the motor easily detaches for speed and ease in disassembly and one-man transportation. More power, more torque, perfectly balanced with drum speed and drum pressure provide a real performance advantage.

Optimum Weight Distribution
Galaxy floor sanders are known for their solid build and weight behind them. This design advantage ensures stability and gives the floor sanding professional an aggressive cut. Optimum weight distribution is critical to performance, as physics testifies. Galaxy machines are ideally balanced keeping the drum fixed on the floor, to deliver the best cut and sanding performance. With our drum pressure mechanism, you can control the depth of cut by simply pulling a lever. No external weights are required.

Belt Tension Mechanism

Galaxy machines have a self-aligning and externally adjustable belt tension mechanism that allows the operator to adjust belt tracking during machine operation. Minimal interruption required for belt tracking adjustments.

Dustless Elbow
